<span>Suppose a triangle had two right angles.
The sum of all angles of any triangle is 180</span>°.
The measure of a right angle is 90°.
By difference, the measure of the other angle can be determined.
Since the two angles have a measure of 90° each, then by difference, the measure of the third angle is 180° - (90° + 90°) = 0°.
If the angle is 0°, there would only be two sides.
A triangle has three sides.
Therefore, a triangle can't have two right angles.
Answer:
b.
Step-by-step explanation:
B because the slope of f(x) is 1 yet the slope of g(x) is 1/3
Answer:
A, B and E
Step-by-step explanation:
y = (1/2)x has the form y = kx, with k = 1/2, its constant of proportionality.
A) 6y = 3x
y = (3/6)x
y = (1/2)x
B) We have to find the slope of the line. Using points (0,0) and (4, 2)
slope = (2 - 0)/(4 - 0) = 1/2
C) We have to find the slope of the line. Using points (0,0) and (2, 4)
slope = (4 - 0)/(2 - 0) = 2
D) We have to find the slope of the line. Using points (2,1) and (4, 3)
slope = (3 - 1)/(4 - 2) = 1
E) We have to find the slope of the line. Using points (4,2) and (10, 5)
slope = (5 - 2)/(10 - 4) = 1/2
